Can we put translation in the sidebar?

The sidebar currently has the historical subtitles. Many of the films I want to watch don’t have Spanish as a subtitle language, so I depend on the translator to present them to me in Spanish. It would be nice to be able to have the translated text in the sidebar, rather than the English subtitles, so I can read back full sentences in Spanish.

I also would like to be able to save translated text, rather than the subtitle - for the same reason, I’m viewing Netflix subtitles in English and would like to save the translation.

Can either of these be accommodated - am I missing something or does this need to go in as a feature request?
